TUCKER FOR SEWlNG lVlACHlNES.

SPECIFICATION forming part of Letters Patent No. 309,597, dated December23, 1884a Application filed March 17,1884. (No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL D. BERRY, of Columbia, Boone county,Missouri, have invented a new and useful Improvement in Tuckers forSewing-Machines, of which the following is a full and clear description,which will be more readily understood by reference to the accompanyingdrawings, of which- Figure 1 is a perspective view of the tucker inposition on the machiue,with the work passing through and held inposition against the inner edge of the guiding device. Fig. 2 is a planview of the tucker device. Fig. 3 is a side view of the work-plate of asewing-machine with the tucker in position, and showing the presser-footand needle. Fig. 4 is an end View of the work-plate with the tucker inplace.

A represents a plate, made of any suitable material, provided with theslots 13 and B. Through the slot B is passed the milled headed bolt a,which screws into the work'plate of the machine. This slot and bolt areintended to allow a lateral adjustment of the plate A and to secure thesame in position when properly adjusted. The plate A is cut out orrecessed on its inner edge at the part marked 0. This recess is to allowthe plate A to escape the presser-ibot and feed of the machine when theplate is adjusted closely for narrow tucks.

D is a narrow plate of metal or other suitable material. One end of thisplate is turned over at b. The other end of this plate is provided witha threaded bolt brazed or soldered thereto, and standing perpendicularto the plane surface of the plate. This bolt passes through the slot B,and is threaded at the end to receive the milled nut a. This arrangementallows the plate D to be adjusted by sliding it inwardly or outwardly inthe countersunk channel, (marked on the drawings, Fig. i, with theletter (1.) This channel is about the depth of the thickness of theplate D, and arranged so that the plate may be easily adjusted andsecured in place by tightening the nut a. The inner edge of the plate A(marked 0 on the drawings) is the guide along which the work passes, andat the same time marks the point at which the work is turned over inpreparing the width of the tuck. The plate A is also provided with theprojecting piece or finger E, which projects over the tuck and assiststhe right hand in keeping the work down and in place.

F is the material in which the tuck is to be formed, and H is thepresser-foot of the ma chine with the needle passing through it.

The operation of the device is as follows: Before beginning to work withthe tucking device I make one tuck by hand, as follows: The materialinto which the tuck is to be sewed is first turned and folded. Thefolded edge is then placed against the inner or guiding edge, e, of theplate A, passing under the projecting piece or finger E. Thepresser-foot is then placed upon the work. The plate A has beenpreviously adjusted so that the distance between the guiding-edge e andthe needle of the machine will regulate the width of the tuck. The workis then run through the machine, taking care to keep the work folded byusing the right hand with its edge against the guiding-edge c. In thisway the first tuck is made, the plate D being adjusted so that the innerend of the hooked or bent-over portion b will be at a distance from theneedle corresponding with the space between the tucks. The work is thenturned around, and the tuck just made by hand is placed under the hookZ) of the plate D until the sewed seam lines with the inner edge of thehook I), as shown in Fig. 1. This scam I have marked 0. The end of thematerial F is then turned over, and, with the left hand upon the goods,placed so as to keep the tuck just made in position and under the hookedpart I) of the plate D and the stitched seam in line with and againstthe inner edge of the hook I), the right hand holding the work so thatits opposite edge, properly turned and adjusted under the presser-foot,passes closely against the guiding-edge e and smoothly under theprojecting linger E. Thus the second tuck is formed, and so oncontinuously until the re qnired'number of tucks is completed.

A tucking device constructed and operating in the manner above describedrenders it unnecessary to mark the work in any way preparatory totucking, and enables the operator to work on linen, cotton, woolen, orother material, avoiding the common trouble of having the work thrownout of place by the pinching or marking device, or torn or injuredthereby,

and the further difficulty of light marking, frequently so faint as notto show upon the material.

This device is simple, serviceable, and accurate, and contains no movingparts to confuse the operator while at work.

I am aware that tuckers have heretoforebeen made with an adjustablefinger adapted to proj ect beyond the edge of the plate, and that saidbase-plate has been cut away to admitthe gageplate sliding therein; butin all such constructions, so far as I am aware, the device was so madethat the gage-plate was fitted in a recess cut in the top of thebase-plate; consequently, there was the thickness of the material ofwhich the base-plate was formed between the gageplate and the table.This was found objectionable, for the reason that the work wasnecessarily raised above the table, whereas the work should lie as closeas possible to the table; and it very often happened with some machinesthat the gage-plate, owing to its being raised above the table, would bein the way of the presser-foot. To avoidthese difficulties I form therecess d on the under side of the plate A, which arrangement allows theplate D to rest on the table of the machine, soas not to raise thematerial but a trifle above the table, and where it is out of the way ofthe presserfoot. I

"What Iclaim, and desire to secure by'Letters Patent, is-

1. In a tucking device forsewing-niachines, the plate A, provided withthe recess (1 on its under side, the adj Listing-slots B and B for thesecuring-bolts a and a, the guiding-edge e, the fixed projecting fingerE, and recess 0, in combination with the plate D, having upturned endI), substantially as described.

2. In a tucking device for sewing-machines, the plate A, provided withthe recess 01 on its under side, the adjustingslots l3 and B for thesecuring-bolts a and a, the guiding-edge e, and the projecting finger E,in combination with the plate D, provided with the upturned hook 1),arranged as described and operating as set forth.
